SUPPORT FOR CAR-HEATER GRATES.

SPECIFICATION forming part of Letters Patent No. 380,544, dated April 3, 1888.

Original application filed April 1?, 1885, Serial No. 162,625. Divided and this application filed June 2-2, 1886. Serial No. 205,859.- (No modem 2b (1.22 whom it may concern:

Be it known that I, WILLIAM C. BAKER, of the city and State ofNew York,have invented an Improvement in Supports for Gar-Heater 5 (grates, of which the following is a specificaion.

This application is a division of a former application for which a patent was granted to me December 7, 1886, No. 353,839; and the present invention relates to the construction of thelower portion of the car-heater, in which the ash-pit iuclosure, bottom plate, and hearth are combined with a ring above the ash-pit having pendent loops closed at their lower 1 ends, a triangular bracket having two arms passing into the pendent 1oops,with an intermediate third arm bearing upwardly against the under side of the ring, and horns projecting upwardly at the apex, and a grate having a central opening and cross-bar resting between the horns ofthe bracket,so that it can be shaken and swung thereon for dumping the ashes.

In the drawings, Figure 1 is a vertical see- 2 tion of the heater complete. Fig. 2 is a sectional plan View below thelinerc Fig. 3 is a perspective view of the bracket for supporting the grate. Fig. 4is a separate View through the grate and at right angles to Fig. 1, and

0 Fig. 5 is an inverted plan of the supportingbracket and of the center part of the grate.

The bottom plate, K, is provided with suitable legs or feet, by which it is to be bolted securely to the floor of the car, and this bottom 3 5 plate, K, is nearly circular at one side; but at the other side it projects in the form of a concave hearth, 76. Upon the surface of this bottom plate, K, is a circular recess or rib, receiving the segment of a cylinder, H, which incloses the ash-pit,except a comparatively narrow opening at the middle part of the hearth 7t, and there is a sliding segment or door, h, to close this opening, except when access is desired to the ash-pit, at which time this seg- 5 ment h is slid to one side.

Resting upon the segment H is the base-ring G, the central portion of which is open, and there is a circular range of openings around the same at (l. The lire pot B rests upon this basering 0, and there is a circular rib,2,upon this 0 base-ring outside the fire-pot and between it and the casing F. The circular range of openings (l is outside this casing F, and it is within the external jacket, E, so that there is an airspace between the jacket E and the case F, through which air ascends and passes out through openings 3 in the top plate, S, and this top plate, S, rests upon the case F and jacket E, and there are bolts at 4, passing up through the base-ring G and through the top plate, S, by which the heater is firmly bolted to the door of the car.

The safety-grate U, the escape flue T, and the conical base T to said flue, and the parts therewith connected, being set forth in my aforesaid patent, are not herein claimed, and do not form a necessary part of this invention.

The portion of the ring 0 which projects in- Wardlyinside the fire-pot Bis sufficiently wide to form a support for the bottom of the heater or heater-coil A, and hence the open space in the middle of the ring 6 is of less diameter than the internaldiameter of the said coil at the bottom thereof. This allows the circular grate Lto be turned up edgewise in dumping the clinkers. At oneside this ring 0 is notched, and the loops n hang below the notched portions.

The bracket M is triangular and terminates at the apex with two prongs or horns, r s. Two of the arms of the triangular bracket- M drop into the pendent loops n, and the third arm of the said bracket passes back beneath the base-ring G and is turned upwardly, as at o. This allows for the removal of the bracket by lifting up the middle portion thereof,or for placing this bracket in the proper position by entering the end 0 beneath the ring 0 and dropping the other two cnds of the bracket into the loops a. 3

The grate L is circular and provided with radial bars and with projecting teeth around its edge. At the center is an opening having a cross bar, 19, through it, which cross bar passes in between the horns r 8. Upon the 5 under side of the grate L is a loop or mortise for the reception of one end of the T-shaped shaker B. By inserting this shaker the grate can be swung horizontally a short distance,s0

as to shake down ashes, and when it becomes necessary to dump the fire or to remove clinkers the grate is swung upon the cross-bar p by the action of the shaker R until it stands almost vertically, as indicated by dotted lines, Fig. 4. In doing this the ashes are not thrown toward the front of the heater, but toward one side; hence they can be removed with facility bya shovel without falling upon the floor of the car, and the shape of the hearth is dish ing, so that the risk of ashes falling over is lessened; but such ashes can be swept up and removed with facility from the hearth and ash-pit.

It will be seen that the foregoing ad vantages result from the bracket M extending to one side away from the front opening and hearth, asseen in Fig. 2, and being supported by the base-ring 0, so as to allow for removing ashes and clinkers without risk of their falling out closed at their lower ends, the triangular bracket having two arms passing into the pendent loops, and the intermediate third arm bearing upwardly against the under side of 0 the ring, and the horns projecting upwardly at the apex, and the grate having a central opening and cross bar resting between the horns of the bracket, substantially as specified.

Signed by me this 18th day of June, A. D. 1886.
